Jessica Alba is well into her second pregnancy, and while she eagerly awaits the birth of her new baby, she’s more than willing to talk about how it’s affecting her famously fabulous bod… and her sex life!

Jess lends her lovely face to the cover of the August issue of Allure, and laments:

“My body’s just different. The jeans just sort of zip up differently, and things hang differently. It’s a miracle what happens, but you definitely are different afterward. Unless you’re Gisele.”

Ill-zipping jeans are a small price to pay for a bundle as cute as her two-year-old daughter, Honor Marie, with husband Cash Warren. But Ms. Alba also shares that she’s experienced a very unexpected (and very hot) side effect of becoming a mom: a better sex life! She says:

“I was quite shy with it. It wasn’t something I embraced until I had my daughter. I saw how incredible and amazing it is to be a woman and to be able to create a life. There’s a reason why certain areas of the body are desirable – because it all leads to reproduction.”
